Empires of the Undergrowth is a fast paced real-time strategy game based on the world of ants, with a story told in a TV documentary style. Built on top of a simulation, the player influences the colony behaviour rather than directly controlling it.
Underground the player excavates their nest, stores food and builds an army. On the surface they claim territory, gather food, overwhelm insects and arachnids and clash with another colony in a tug-of-war battle. Army size, composition and attack timing will eventually lead to one army pushing into the nest of the other to defeat their queen.
